[0025] Please refer to Figures 1 to 3 , the embodiment of the present application provides a spraying device, and the spraying device may include: a device mounting frame 1, a lead screw 2, a mating shaft 3, a moving block 4, a motor 5, a horizontal driving mechanism 6, and a spraying assembly 7. Among them, the device mounting frame 1 is vertically arranged and has a first connecting seat 101 and a second connecting seat 102 arranged oppositely; the lead screw 2 is rotatably arranged between the first connecting seat 101 and the second connecting seat 102; the mating shaft 3 is fixed between the first connecting seat 101 and the second connecting seat 102 and is located on one side of the lead screw 2; the moving block 4 is in threaded cooperation with the lead screw 2 and in sliding cooperation with the mating shaft 3; the motor 5 is fixed on the second connecting seat 102 and is connected to one end of the lead screw 2; the horizontal driving mechanism 6 is connected to the moving block 4; the spraying assembly 7 is connected to the horizontal driving mechanism 6.

[0026] In some exemplary embodiments, a first bearing is provided between the lead screw 2 and the first connecting seat 101; a second bearing is provided between the lead screw 2 and the second connecting seat 102.

[0027] In this embodiment, when a battery car catches fire, the spraying assembly 7 is opened to spray water on the burning battery car. During the water spraying process, both the motor 5 and the horizontal driving mechanism 6 are started. Specifically, the motor 5 is started to drive the lead screw 2 to rotate. The rotation of the lead screw 2 can drive the moving block 4 to move up and down. The up and down movement of the moving block 4 can drive the horizontal driving mechanism 6 to move up and down, thereby driving the spraying part of the spraying assembly 7 to move up and down. At the same time, the horizontal driving mechanism 6 is also started to drive the spraying part of the spraying assembly 7 to move horizontally, so as to spray water to every corner of the battery car, thereby achieving rapid fire extinguishing. This design can effectively improve the uniformity and efficiency of spraying and achieve a better fire extinguishing effect.

[0028] It should be noted that when the spraying device involved in this application extinguishes the fire of the battery car, it will spray water on the body of the battery car, rather than on the battery of the battery car. During the fire extinguishing process, the spraying assembly 7 will not directly spray water on the battery part under the drive of the driving assembly, but indirectly cool the battery by spraying water on the body to control the combustion of the battery.

[0029] Please refer to Figure 1 , the lead screw 2, the mating shaft 3, the moving block 4, the motor 5 and the horizontal driving mechanism 6 constitute a driving assembly, and multiple groups of driving assemblies are provided.

[0030] In this embodiment, the driving assembly composed of the lead screw 2, the mating shaft 3, the moving block 4, the motor 5 and the horizontal driving mechanism 6 is set to be multiple groups, so that multiple battery cars can be parked at the same time, enhancing the practicability of the device.

[0031] Please refer to Figure 1 , the horizontal driving mechanism 6 may include: a mounting seat 601 and a driving cylinder 602. Among them, the mounting seat 601 is fixed on the side of the moving block 4 facing the spraying assembly 7; the driving cylinder 602 is fixed on the mounting seat 601, and the piston rod of the driving cylinder 602 is connected to the spraying assembly 7.

[0032] Among them, the horizontal driving mechanism 6 can accurately control the horizontal spraying of the spraying assembly 7 according to a preset program or an external control signal, realizing the dynamic adjustment of the spraying range. As a mature pneumatic component, the driving cylinder 602 has the advantages of fast response, high control precision and simple maintenance, and is very suitable for occasions of automatic control. At the same time, the use of the mounting seat 601 ensures the stability and reliability of the installation of the driving cylinder 602, reduces the vibration and displacement during the movement process, and improves the precision and efficiency of the overall device.

[0033] Please refer to Figure 1 , the spraying assembly 7 may include: a water storage tank 701, a main spray pipe 702, spray branch pipes 703 and spray heads 704. Among them, the water storage tank 701 is filled with spraying water, and the water storage tank 701 is arranged on one side of the device mounting frame 1; the main spray pipe 702 is communicated with the water storage tank 701; one end of the spray branch pipe 703 is communicated with the main spray pipe 702; the spray head 704 is communicated with the other end of the spray branch pipe 703. A switch (which can be an electromagnetic valve) is arranged inside the spray head 704, and the spray head 704 is connected to the piston rod of the driving cylinder 602.

[0034] Specifically, during spraying, driven by the driving device, the spraying water comes out of the water storage tank 701, passes through the main spray pipe 702 to reach the spray branch pipes 703, and finally reaches the spray heads 704 and sprays out the water. During the whole spraying process, the switch arranged inside the spray head 704 is in the normally open state. Connecting the spray head 704 to the piston rod of the driving cylinder 602 can effectively realize the horizontal forward and backward movement of the spray head 704 on the basis of the up and down movement, and can spray the burning battery vehicle without dead angle to achieve the effect of extinguishing the fire in the shortest time.

[0035] Please refer to Figure 1 , a downwardly bent end spray pipe 705 is arranged at the output end of the spray head 704, and a shower head 706 is arranged at the end of the end spray pipe 705.

[0036] In this embodiment, setting the end spray pipe 705 as a downwardly bent pipe is beneficial for the end spray pipe 705 to be aligned with the burning battery vehicle; arranging the shower head 706 at the end of the end spray pipe 705 can evenly spray the water inside the end spray pipe 705 on the burning battery vehicle to ensure that there is no dead angle and all parts of the battery vehicle can be sprayed.

[0037] Please refer to Figure 1 , a pipe connection plate 708 is fixed on the device mounting frame 1, and the main spray pipe 702 is fixed on the pipe connection plate 708; among them, the main spray pipe 702 is a rigid pipe, the spray branch pipes 703 are flexible pipes, and a water pump 707 is arranged on the main spray pipe 702.

[0038] Among them, the setting of the pipe connection plate 708 enables the main spray pipe 702 to be connected to the device mounting frame 1, thereby making the main spray pipe 702 more stable. Setting the main spray pipe 702 as a rigid pipe is beneficial for the spraying water to flow in the pipe, while setting the spray branch pipes 703 as flexible pipes is convenient to ensure that the spray heads 704 can move smoothly in the horizontal direction and also move smoothly in the vertical direction when spraying the burning battery vehicle.

[0039] It should be noted that the length of the spray branch pipe 703 is such that the moving block 4 moves vertically to the lowest position of the device and the spray head 704 moves horizontally to the most forward position.

[0040] Please refer to Figure 2 、 Figure 3 The spray device may further include: a plurality of partition plates 8, wherein the plurality of partition plates 8 are evenly spaced on the device mounting frame 1 and correspond to the drive assembly; the spray structure of the spray assembly 7 is located between two adjacent partition plates 8.

[0041] Among them, the plurality of partition plates 8 are all made of refractory materials. In this embodiment, by providing a plurality of partition plates 8 to separate individual spray units, an electric vehicle can be placed for charging between two adjacent partition plates 8. During the charging process, if a fire occurs in one of the electric vehicles, the presence of the partition plates 8 prevents other electric vehicles from being ignited.

[0042] Please refer to Figure 2 A temperature sensor 801 is provided on one side of the partition plate 8 facing the spray structure of the spray assembly 7.

[0043] Specifically, when a fire occurs in an electric vehicle, since the temperature sensor 801 is provided on the partition plate 8, it can detect the temperature change and send the signal to the control device in time, and the control device controls the spray head 704 to open for fire extinguishing.

[0044] Please refer to Figure 2 、 Figure 3 The spray device may further include: a top plate mounting portion 9, a top plate 10, a bottom plate mounting portion 11, and a bottom plate 12. Among them, the top plate mounting portion 9 is fixed to one side of the device mounting frame 1 close to the motor 5; the top plate 10 is fixed to the top plate mounting portion 9 and is located above the spray assembly 7; the bottom plate mounting portion 11 is fixed to the side of the device mounting frame 1 away from the motor 5; the bottom plate 12 is connected to the bottom plate mounting portion 11 and is disposed opposite to the top plate 10; wherein, a camera 13 is provided on one side of the top plate 10 facing the bottom plate 12, and the end of the bottom plate 12 is provided with an inclined surface structure.

[0045] In this embodiment, the setting of the top plate 10 can prevent the spray device from being exposed to rain or sunlight and can provide a certain degree of protection for the electric vehicle; the setting of the bottom plate 12 is beneficial to directly placing the entire spray device on the ground to ensure the stability of the entire device; the setting of the camera 13 can monitor the electric vehicle parked under the spray device in real time to avoid the situation of vehicle theft.

[0046] Please refer to Figure 1, the spraying device may further include: a controller 14 and a speaker 15. Among them, the controller 14 is fixed to one side of the device mounting bracket 1, the controller 14 is electrically connected to the switch inside the spray head 704, and the controller 14 is electrically connected to the driving cylinder 602; the speaker 15 is fixed to one side of the device mounting bracket 1 and is electrically connected to the controller 14.

[0047] Among them, by setting the controller 14, when a fire occurs in the battery vehicle under the spraying device, the switch inside the spray head 704 is opened under the control of the controller 14 to extinguish the burning battery vehicle. At this time, the driving cylinder 602 also makes a telescopic movement under the control of the controller 14, and the speaker 15 starts to alarm under the control of the controller 14.

[0048] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
